    LCoS-Based Wavelength-Selective Switch for Future Finer-Grid Elastic Optical Networks Capable of All-Optical Wavelength Conversion by Dequan Xie, Danshi Wang, Min Zhang, Zichen Liu, Quan You, Qi Yang, Shaohua Yu

    Published 2017-01-01

    A finer-grid wavelength-selective switch (WSS) based on liquid crystal on silicon is proposed, fabricated, and demonstrated. Based on the cost-effective method, namely combined lenses technique, the focal length is increased so that both the bandwidth setting resolution and grid granularity is impro...

    Low-Observability Distribution System State Estimation by Graph Computing with Enhanced Numerical Stability by Zijian Hu, Hong Zhu, Lan Lan, Honghua Xu, Zichen Liu, Kexin Li, Jie Li, Zhinong Wei

    Published 2025-06-01

    In distribution systems, limited measurement configurations and communication constraints often result in a low success rate of data acquisition, posing challenges to both system observability and the real-time performance required by state estimation (SE). Consequently, the distribution system SE (...
